Abstract: Various examples are directed to systems and methods for distributed transactions with extended locks. A transaction node may receive from a coordinator node an instruction to execute an assigned operation on an object. The assigned operation may be part of a distributed transaction. The transaction node may obtain a lock associated with the object and execute the assigned operation. The transaction node may also set a time-to-expiration of a lock timer to an initial value and start the lock timer. When the transaction node determines that the lock timer has expired, it may release the lock.

Abstract: A system and method of loss prevention using a pair of ID tags is disclosed. The user or owner of the protected object can dynamically create a security perimeter by using key ID tag and object ID tag pair. An object ID tag is either embedded in or attached to a protected object. A key ID tag, which is in a handheld device, has protection to prevent unauthorized scan. The object ID tag information can only be obtained from key ID tag using preprogrammed algorithm. The area security system will be armed after reading and validating a key ID tag scanned by the user. If anyone takes protected object with object ID tag out of the area without proper key ID tag authentication, alarm will be triggered.

Abstract: Content items queued for synchronization between a client device and a content management system can be automatically prioritized to improve the sharing process. That is, the content items can be prioritized based on whether a share link has been created to the content item. A share link can enable a user to access the shared content item from a content management system. Content items that have been shared using a share link can be given higher priority to be synchronized prior to content items that have not been shared. The queued content items can be synchronized in the synchronization order resulting from the prioritization. Further, multiple shared content items queued for synchronization can be sub-prioritized based on one or more sub-prioritization criteria.

Abstract: Technologies are generally described for methods and systems to join a first source dataset with a second source dataset. In an example, a processor may receive a request to join the first and second source datasets based on a condition. The processor may determine a first range of attribute values from the first source dataset, and a second range of attribute values from the second source dataset. The processor may produce a filtered dataset based on a comparison of the first and second ranges. A map unit may transform the filtered dataset and the second source dataset into first and second mapped datasets based on the condition. A reduce unit may transform the first and second mapped datasets into first and second reduced datasets based on the condition. A combiner unit may combine the first and second reduced datasets to join the first and second source datasets.

Abstract: For self-healing in a hash-based deduplication system using a processor device in a computing environment, deduplication digests of data and a corresponding list of the deduplication digests in a table of contents (TOC) are maintained for the self-healing of data that is lost or unreadable. The input data digests are compared to the TOC if directed to data that is lost or unreadable, and the input data digests are used to repair the one of lost and unreadable data.

Abstract: A novel system for automatically indicating the specific identity of ambiguous named entities is provided. An automatic disambiguation data collection is created using a reference resource. Explicit named entities are catalogued from the reference resource, together with various abbreviated, alternative, and casual ways of referring to the named entities. Entity indicators, such as labels and context indicators associated with the named entities in the reference resource, are also catalogued. The automatic disambiguation collection can then be used as a basis for evaluating ambiguous references to named entities in text content provided in different applications. The content surrounding the ambiguous reference may be compared with the entity indicators to find a good match, indicating that the named entity associated with the matching entity indicators is the intended identity of the ambiguous reference, which can be automatically provided to a user.

Abstract: Technology is disclosed for accessing data fragments of data objects. The method receives a request for storing a data fragment of a data object in the storage server. The request includes an object identifier of the data object. The method further extracts a first string from the object identifier.

If there is no file system object that has a file system name that matches the first string, the method stores the data fragment as a fragment file with a file system name matching the first string.
